Where can you read Watchmen online for free?

you probably can but it's not a good idea. not on the legal repercussions but because most of the serious fans would be tempted to kick your ass for not giving Alan Moore what he deserves.

let me put it simply, you have a wonderful piece of literature that is adored by many and you find out that some of your so called "fans" couldn't even be bothered to go out and buy the book. if you really want to read it you are really going to want to own it. and if you still feel that it isn't wort your while to buy the book than you shouldn't see the movie. you should try categorizing your answer, then again, i couldn't find a place for blaspheme ether.
